Porous poly(methacrylic‐ co ‐glycidylmethacrylate) (MAA‐GM) was prepared by dispersion polymerization using benzoyl peroxide as an initiator and methacrylate terminated phthalate glycol polyester as a steric stabilizer in polar organic medium (chloroform–ethanol mixture). The prepared poly(methacrylic acid) dispersion was crosslinked by glycidylmethacrylate oligomers. The crosslinked copolymer (MAA‐GM) was base hydrolyzed using hydroxyl amine, sodium methoxide, and triethyl amine. The metal binding behavior of the prepared polymer was examined by means of atomic absorption spectrophotometer. The thermal stability of the prepared polymers was examined by thermal gravimetric analysis (TGA). © 1999 John Wiley & Sons, Inc. J Appl Polym Sci 73: 1793–1798, 1999
